hardback

There are still traditional readers but, even for them, the hardback library books may evolve in the near future..这仍有一般的读者，但即使是对他们来说，精装的图书在不远的未来也可能有了变化。

I prefer paperback or hardback books for pleasure reading but, for research, I prefer a device with access to the Internet..娱乐性阅读时我更喜欢平装或者精装的纸质书，但如果是做研究，我更喜欢可以连入互联网的设备。

Self Portrait, from 1630, is one of only five paintings he executed on copper, and one of his smallest, the size of a hardback book..1630年自画像是他的五幅镀金铜版画之一，也是最小的画作之一，只有精装书大小。
